Lawn Weed Control in Tampa

Sometimes chemicals are required for weed control. A herbicide is any chemical which injures or kills a plant. Herbicides are safe and effective if product label instructions are followed. Herbicides are classified based on how and when they control weeds.

A selective herbicide controls certain plant species without seriously affecting the growth of other plant species. The majority of herbicides used are selective herbicides.

Non-selective herbicides control green plants regardless of species. These are generally used to kill all plants, such as in the renovation or establishment of a new turf area or as spot treatment or as a trimming material along sidewalks.

Contact herbicides affect only the portion of green plant tissue that is contacted by the herbicide spray. These herbicides are not translocated or moved in the vascular system of plants. Therefore, these will not kill underground plant parts, such as rhizomes or tubers. Repeat applications are often needed with contact herbicides to kill regrowth from these underground plant parts.

Systemic herbicides are translocated in the plant's vascular system. The vascular system transports the nutrients and water necessary for normal growth and development. Systemic herbicides generally are slower acting and kill plants over a period of days.
